Answer:

x=15

Step-by-step explanation:

7x+3x-4=146

10x-4=146

10x=150

X=15

The two sides added up equals the outside length.

Rewrite one tenth times x cubed times y plus two tenths times x times y squared using a common factor.

zalisa [80]

The expression which can be rewritten using a common factor is; xy/10 (x² + 2y).

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

We have the following information given as;

One tenth times x cubed times y plus two tenths times x times y squared using a common factor.

We know that 'times' has to be replaced with multiplication.

Now, we will change this into mathematical expression as;

x³y/ 10 + 2xy²/ 10

Now, the common factor can be ;

xy/10

The Common factor refers to the number and the variables taken as a common factor should be able to completely divide the terms given any expression.

Now, taking it as a common factor, we have the following expression:

xy/10 (x² + 2y)

Hence, the required expression is; xy/10 (x² + 2y).

Answer:

ornament area = 379.8 cm²
paint needed: 114 bottles

Step-by-step explanation:

The surface area of one cone with slant height s and radius r is ...

SA = πr² +πrs = πr(r+s)

For the cone that is half an ornament, the surface area is ...

SA = (3.14)(4.2 cm)(4.2 cm + 10.2 cm) = 189.9072 cm²

The area of one ornament is the area of two cones:

one ornament area = 2×189.9072 cm² ≈ 379.8 cm²

60 ornaments will be 120 cones, so will have a total surface area of ...

total area = 120(189.9072 cm²) = 22,788.864 cm²

If one bottle of paint will cover 201 cm², then the number of bottles of paint required is ...

(22788.864 cm²)/(201 cm²/bottle) ≈ 113.4 bottles

Divide.<br><br> −2 4/7<br><br> Enter your answer as a mixed number, in simplified form, in the box.

Katarina [22]

Answer:
-3 $\frac{3}{7}$

Explanation:
$\frac{-24}{7}$ = -3 $\frac{3}{7}$
So first make the improper fraction into a mixed number by taking out all the whole numbers from the numerator (3) and making sure the proper sign is in front of the answer (- 3) your remainder is the original numerator minus the product of the answer times the denominator: 24 - (3 • 7) = 24 - 21 = 3. Rewrite the mixed number.

The correct answer is: Commutative Property

Further Explanation:

The commutative property states that the order of number doesn't matter and changing the order of numbers or variables will produce the same result.

<u>Commutative Property of Addition:</u>

The Commutative Property of addition means that an expression can be written as a + b = b + a.

<u>Commutative Property of Multiplication:</u>

The Commutative Property of multiplication means that an expression can be written as a • b = b • a

Hence, the correct answer is: Commutative Property

Keywords: Commutative property, addition, multiplication
